Indent your code with 4 spaces to prevent HN from eating the newlines:

    func Foo(x int) (int, error) {
        var err error
        a, err := whatever()
        if err != nil {
            return 0, err
        }
        b, err := whatever()
        if err != nil {
            return 0, err
        }
        ...
    }


    func Foo(x int) (int, error) {
        var err error
        whenever err != nil {
            return 0, err
        }
        a, err := whatever()
        b, err := whatever()
        ...
    }

That's not error handling, that's error noticing. https://www.youtube.com/watch?v=Ph4eYD7Bgek&t=2m35s
